NASA’s Astronomy Picture of the Day

In today's image, we see an active galaxy known by its catalog designation NGC 1275. An active galaxy differs from an ordinary galaxy in the it emits more energy and different types of energy than a typical galaxy.

In today's image, we see what is sometimes known as the Boogeyman Nebula. This is part of the Orion star forming region, about 1500 light years from Earth. We see the dark nebula as well as the red glow of hydrogen gas in emission nebulae.

In today's image, we see an image generated by artificial intelligence of what the surface of a specific Earth-sized exoplanet might look like. We can use the information we know about the object to make an educated guess as to what this might look like. Over 5000 exoplanets have now been detected and the technology is improving so we are finding more and more that are potentially like Earth.

In today's image, we see two galaxies in the process of colliding together in what is known as Arp 274. Galaxy collisions involve the collisions of gas clouds when can enhance star formation. However, the stars themselves actually rarely if ever collide.

In today's image, we see an image showing an auroral display from early 2014. The aurora occur when charged particles from the Sun, often from a solar flare, strike Earth's atmosphere and are the funneled along the magnetic field toward the north and south magnetic poles. When the strike oxygen atoms in Earth's upper atmosphere, the tree glow is produced.

In today's image, we see comet ZTF as imaged just a couple of days ago. The comet has brightened enough and is now visible to the naked-eye from a dark site with little light pollution. It should continue to brighten as it reaches closest approach to Earth on Feb 2. However, it will not come anywhere near close enough to Earth to have any chance to impact!

In today's image, we see two galaxies: M81 - a spiral galaxy and M82 - an irregular galaxy. These are two galaxies that are interacting, enhancing star formation in both galaxies. In a few billion years, the two galaxies will merge, creating a single, larger galaxy.

In today's image, we see the Seagull Nebula, a star forming region in the constellation of Canis Major, the large dog. This constellation also contains the brightest star in the night sky, Sirius. We see the gas and dust of the star forming region as well as a runaway star with its blue bow shock.

In today's image, we see the lensing of a distant group of galaxies by a foreground cluster. Three different images of these galaxies are formed as light travels through the region of space distorted by the cluster of galaxies. From Hubble, only a single object was able to be seen. However, the more powerful Webb Telescope is able to resolve this into two or more galaxies dating back to the early history of the universe only a few hundred million years after the Big Bang.

In today's image, we see the Andromeda Galaxy which is the nearest large spiral grassy to our own Milky Way. The clouds to the lower left are recently discovered and we do not yet know their origin or wether they are located close to Andromeda or within our own Milky Way galaxy. Future studies may be able to tell us something new about the universe.
